Abstract
Semiconductor oxides such as $TiO_2$ involved in light conversion efficiency are the main elements of dye-sensitized solar cells (DSSC) and are used to mix different semiconductor oxides to improve efficiency. In this research, characteristics of the dye-sensitive solar cell are studied using semiconductor oxide formed by mixing $TiO_2$ and $Nb_2O_5$. A solar cell is manufactured by adding $Nb_2O_5$ at different ratios in order to analyze electrical characteristics of a mixed semiconductor oxide on light conversion efficiency. With the addition of $Nb_2O_5$, the conductivity was further enhanced than the recombination phenomenon caused by contact with electrolytes, confirming the improve of short-circuit, open voltage, and conversion efficiency of solar cells.
